Hello Chinenye,
Have you considered using an alternative method of disinfection?
Have a look at this product
http://www.ecabiotec-me.com/images/uploads/general/ANOSAN-TW-Product-Profile.pdf
and see if it might work for you. It is for both small and large scale use, has readily available monitoring and dosing systems and, above all, is environmentally friendly and is safe for humans, animals, birds, fish etc. It is so safe that you can even drink it.
It also removes the biofilm in the distribution network and needs no flushing other than to rid the pipeline of released dirt/slime.
UV is good, chlorine is old hat and Ecabiotec is excellent!
